F. No. GST/INV/DIN-Utility/2022-23
Government of India

Department of Revenue
(Central Board of Indirect Taxes and Customs)
New Delhi, Dated – 23

September 2025.
Subject: Communication to taxpayers through eOffice - requirement of Document
Identification Number (DIN) - reg.
Attention is invited to Board's Circular No. 122/41/2019- GST dated 05
th
November
2019 and 128/47/2019-GST dated 23
rd
December 2019 regarding Generation and Quoting of
Document Identification Number (DIN), initially on specified documents and subsequently
expanded to all communications (including e-mails) sent to taxpayers and concerned persons.
2. Attention is also invited to subsequent Board's Circular No. 249/06/2025-GST dt. 09
th
June 2025 clarifying that for communications via GST common portal (in compliance with
Section 169 of the CGST Act, 2017) having verifiable Reference Number (RFN), quoting of
Document Identification Number (DIN) is not required and such communication bearing
RFN is to be treated as a valid communication.
3. On similar lines, it has been brought to the notice of the Board that communications
issued through eOffice of CBIC bear an automatically generated unique ‘Issue number’.
However, no online utility was available to verify the authenticity of such communications
through Issue number, hence DIN was required to be generated and quoted on such
communications. Now an online utility has been developed and made functional
(URL https://verifydocument.cbic.gov.in ) , where the taxpayers and other concerned persons
can verify online the electronically generated unique “Issue number” borne on
communications dispatched using public option in eOffice application by CBIC officers.
Upon verification, this utility confirms the Issue number, and other details and provides
information to authenticate the document, like, -
i.File number,
ii.Date of issuing the document,
iii.Type of communication,
iv.Name of Office issuing the document,
v.Recipient name (masked),
vi.Recipient address (masked),
vii.Recipient email (masked).
4. The name of the office issuing the document is captured from the data available
within eOffice, while the document type, recipient name, recipient address, recipient email
GST/INV/DIN-Utility/2022-23 I/126773/2025

are entered in the metadata by the officers creating the document. Officers responsible for
issuing communications via CBIC's eOffice must mandatorily fill and ensure correctness of
this information in the metadata while creating the draft before its approval.
5. In light of the above, quoting separate DIN on such communications dispatched using
public option in eOffice application, which already bear issue number, will result into two
different electronically generated verifiable unique numbers namely Issue No. & DIN on the
same communication, which renders quoting of separate DIN on such communication
unnecessary. It is therefore decided that for communications dispatched using public
option in CBIC’s eOffice application, the verifiable eOffice ‘Issue number’ shall be
deemed to be the Document Identification Number and such communication shall be treated
as a valid communication.
6. The Document Identification Number generated through DIN utility shall continue to
be mandatorily quoted on all other communications which have either not been dispatched
using public option in CBIC’s eOffice application or which do not bear the verifiable
Reference Number (RFN) generated on GST common portal.
7. To the above extent, Circular No. 122/41/2019- GST dated 05
th
November 2019,
Circular No. 128/47/2019-GST dated 23
rd
December 2019 and Circular No. 249/06/2025-
GST dated 09
th
June 2025 issued by the Board, stands modified.
